一：集中式编写lnmp剧本

vim /etc/ansible/lnmp.yml- name: lnmp playhosts: dbserversremote_user: roottasks:- name: perpare condifurecopy: src=/etc/yum.repos.d/nginx.repo dest=/etc/yum.repos.d/nginx.repo- name: install nginxyum: name=nginx state=latest- name: start nginxservice: name=nginx state=started enabled=yes- name: install mysqlyum: name=mysql57-community-release-el7-10.noarch.rpm state=latest- name: modify filereplace:path: /etc/yum.repos.d/mysql-community.reporegexp: 'gpgcheck=1'replace: 'gpgcheck=0'- name: install mysql-community-serveryum: name=mysql-community-server state=latest- name: start mysqlservice: name=mysqld state=started enabled=yes- name: add yum filecommand: 'wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm -P /etc/yum.repos.d' - name: rpm epelcommand: 'rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm'- name: rpm el7command: 'rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm'- name: install phpcommand: 'yum install -y php72w php72w-cli php72w-common php72w-devel php72w-embedded php72w-gd php72w-mbstring php72w-pdo php72w-xml php72w-fpm php72w-mysqlnd php72w-opcache'- name: start php-fpmservice: name=php-fpm state=started  enabled=yes- name: copy configurecopy: src=/usr/local/nginx/conf/nginx.conf dest=/etc/nginx/conf.d/default.conf- name: restart nginxservice: name=nginx state=started enabled=yesansible-playbook lnmp.yml  运行

二：分布式安装lnmp

1、nginx 配置

#创建各个服务的节点
vim /etc/ansible/hosts[webservers]
192.168.231.102[dbservers]
192.168.231.103[phpservers]
192.168.231.110#免交互
ssh-keygen -t rsa
sshpass -p '123456' ssh-copy-id  192.168.231.102 #创建文件
mkdir /etc/ansible/roles/nginx/{files,templates,tasks,handlers,vars,defaults,meta} -p
mkdir /etc/ansible/roles/mysql/{files,templates,tasks,handlers,vars,defaults,meta} -p

#编写php测试文件vim /etc/ansible/roles/nginx/files/index.php
<?php
phpinfo();

}

2、mysql配置

vim /etc/ansible/roles/mysql/tasks/init.yml
- name: stop firewalldservice: name=firewalld state=stopped enabled=no
- name: stop selinuxcommand: 'setenforce 0'vim /etc/ansible/roles/mysql/main.yml
- include: "init.yml"- name: remove mariadbshell: 'yum remove mariadb* -y'
- name: wgetshell: 'wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm -P /etc/yum.repos.d'
- name: install mysql57-community-release-el7-10.noarch.rpmyum: name=epel-release
- name: sedreplace: path=/etc/yum.repos.d/mysql-community.repo regexp="gpgcheck=1" replace="gpgcheck=0"
- name: install mysql-community-serveryum: name=mysql-community-server
- name: start mysqlservice: name=mysqld.service state=started
- name: passdshell: passd=$(grep "password" /var/log/mysqld.log | awk 'NR==1 {print $NF}')
- name: mysql 1shell: mysql -uroot -p'passd' --connect-expired-password -e "ALTER USER 'root'@'localhost' IDENTIFIED BY 'admin@123';"ignore_errors: true
- name: mysql 2shell: mysql -uroot -padminabc@123 -e "grant all privileges on *.* to root@'%' identified by 'admin@123' with grant option;"ignore_errors: true

3、php配置

vim /etc/ansible/roles/php/tasks/init.yml
- name: stop firewalldservice: name=firewalld state=stopped enabled=no
- name: stop selinuxcommand: 'setenforce 0'vim /etc/ansible/rolesphp/tasks/main.yml
- include: "init.yml"- name: install yum reposhell: "rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm && rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm"ignore_errors: true

- name: add useruser:name: phpshell: /sbin/nologinsystem: yes
- name: copy php.inicopy: src=php.ini dest=/etc/php.ini

- name: copy index.phpcopy: src=index.php dest=/var/www/html
- name: start php-fpmservice: name=php-fpm state=started

4、运行剧本

vim /etc/ansible/lnmp.yml
- name: nginx playhosts: webserversremote_user: rootroles:- nginx
- name: mysql playhosts: dbserversremote_user: rootroles:- mysql- name: php playhosts: phpserversremote_user: rootroles:- php
